Abstract

A continuous on-line combustion-type carbon analyzer (110) for water applications is provided. The analyzer receives a continuous stream of sample (110) and carbon dioxide-free gas (114). The analyzer (100) includes control components (120) to limit sample (110) flow into a combustion furnace (126) such that excessive pressures and thermal stresses are minimized. The sample specimen is oxidized within the combustion furnace (126) and the oxidized sample is conveyed to a detector (118) that provides a continuous read-out of carbon quantity in the sample stream (110).
